According to studies done by the Minnesota Pollution Control Agency, the lakes and streams across Minnesota are contaminated by

pharmaceuticals, cosmetic ingredients, and endocrine-disrupting compounds. Even in remote areas of the state, chemicals such as antibiotics, nicotine breakdown products, antidepressants, and medications to regulate diabetes, cholesterol, and blood pressure, were detected. The insect repellent DEET was detected in 91% of the lakes studied. Previous studies showed that these compounds often turned up downstream from wastewater treatment plants but recent research has shown that they are also found even in remote lakes or upstream waters.
Researchers believe that these chemicals enter the water table through septic systems and stormwater __________ and are not impacted by wastewater treatment plants.
A) collection
B) pollution
C) runoff
D) treatment

1. Why is the quadrat method useful for estimating snall populations? Explain why the same method would not be useful for counti
irga5000 [103]

Answer:

Quadrat method is used for estimating the number of individuals in an area. In this method, a large square area on the ground or water surface is marked, call it an enclave. The number of animals present in this enclave is counted. Then by assuming that the animals are less migratory and are uniformly distributed, their number for a large area is estimated by the use of unitary method of calculation. Example a 4 square feet area has 2 snails, then a 1000 square feet area will have (1000 x 2)/4, i.e, 500 snails in it. Fishes can be counted using this method only if they are confined in a small water body like a lake or a pond. Rivers are flowing so the fishes may move along its length which can give us an underestimate or an overestimate of their numbers. Sea has its depth and huge area, and fishes can be moving randomly in it. Hence this method will not work for river and sea fishes.

Hope this helps :D
